APPARATUS FOR DISPENSING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 405,846, dated June 25, 1889. Application filed October 23, 1888. Serial No. 288,910. (No model.)

To all whom it may concern:

Be it known that l, JOSEPH CARL MAYE- HOFER, of the city, county, and State of New York, have invented a new and Improved Apparatus for Dispensing Liquids, of which the following' is a full, clear, and exact description.

The object of my invention is to provide a practical apparatus whereby, in exchange for Io a coin or token, a person may obtain a supply of perfumery or other liquid in the form of a spray; and to this end my invention. consists principally of an air-compressing device and atoniizer combined with a coin-tube to receive a coin, and mechanism between the coin-tube and the air-compressing device to operate the air-compressing device when a coin is dropped into the coin-tube, a lock for holding the said mechanism until released by a coin or token 2o dropped into the coin-tube, and an auxiliary locking device for preventing more than one discharge for each coin.

The invention also consists of the construction, arrangement, and combination of part-s,

all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

3o Figure l is a front elevation, partly in section, broken away at the bottom. Fig. -2 is a section on the broken line yy of Fig. l. Fig. 3 is a front elevation. Fig. 4 is a sectional plan View on line e .e of Fig. 3, and Fig. 5 is 3 5 a similar view on line ,2'2" of Fig. 3.

A represents the main frame of the apparatus having horizontal partitions B B. On partition B is placed one or more, preferably three, receptacles C C, for liquid perfumery.

4o In the top of each receptacle C is fitted an ordinary atomizer-tip c, bent so that its discharge end stands in the opening a of the front board A of the main frame of the apparatus. To each atomizer-tip cis attached the discharge-tube d, the lower end of which connects with the cylindrical casing D, in which is fitted a hollow cock D', having apertures e to coincide with the ends of the tubes (l when turned to different positions.

E is a soft-rubber pump-bulb provided with 5o induction check-valvef and eduction checkvalve f. This bulb E is connected by tube Z2 to the soft-rubber bulb or reservoir E', which is surrounded by netting E2 to prevent toogreat expansion of the reservoir-bulb by compressed air forced into it by the pumpbulb E. The reservoir-bulb is connected to the interior of the hollow cock D by a tube d', so that the contraction of the reservoirbulb upon the air contained therein will force 6o a jet of air through one or the other of the tubes CZ when the cock D is turned to bring one of the ports or passages e into line with one of the tubes d. This jet of air forced through the pipe d and atomizer-tip c will force liquid from the receptacles C in the form of spray, upon the principle of the ordinary hand-atomizers.

The pump-bulb E may be compressed and released by various mechanisms; but I pre- 7o fer to employ a treadle G, to be operated by the foot. The bulb is held upon the compressing-plate II, a-dapted to be moved vertically for squeezing the bulb, the resistance being taken by the plate H. The said plate II is operated by levers J K, treadle G, and connecting-rod G, all shown clearly in Fig.

l. Lever J is fulcrumed at j and connected to plate II by rod j', and its rear end is connected to the free end of lever K below 8o by rod j?. Attached to the rear end of the lever J is a pawl stop or rest jg. Lever K is fulcrumed at 7c, and isconnected by coiled spring 7o to lever J and by pin k2 to connecting-rod G', which pin works in a slot k3 of the 85 said rod, so that said rod may have a movement upward, caused by spring g, beneath the treadle G, independently of the said lever K, for the purposes hereinafter described. The lever J is provided at its pivot with a 9o locking-segment m, formed with notch fm', with which the counterbalanced locking-pawl N is adapted to engage to hold the said lever in position to lock the bulb-compressing plate H at its lowermost position. The end of the counterbalanced pawl N is formed or provided with a plate m2, which stands beneath the coin or token tube O, so that when a coin is dropped into the slot it will fall upon the plate mzand lift the' point of the pawl out of contact withthe segment m, thus releasing the lever J. At the time the coin is dropped,

or thereafter, lthe operator places his foot upon the treadle G and forces it down. This will draw down levers K J and force upward the plate H and compress the pump-bulb E, which will force air into the rubber reservoir E. The operator will now place his handkerchief in front of the aperture a and then turn the knob b, which by crank and disk b' b2 will turn the hollow cock D' until one of the apertures e coincides with one of the tubes d, when the compressed air in the reservoir E will be forced out through the atomizer-tip c and cause aspray of perfumery to be deposited upon the handkerchief.

My apparatus is a convenient one to use, fol` the reason that it is not necessary to press down the treadle immediately upon dropping the coin in the slot. `When the coin `falls upon the plate attached to the counterbalanced pawl, the pawl is depressed sufficiently to unlock the lever J, but is prevented by the stop or rest jg from being depressed so far as to cause the coin to slip oif from the plate.

The coin remains on the plate, and thus keeps the lever J unlocked, until the treadle is depressed and the pawl-stop lowered, when the pawl sinks to its lowest position andthe coin drops into the coin-box, releasing the pawl, which returns to its locking position. This is one important feature of my invention.4

In order to prevent more than one operation for each coin, I provide the lever K with a locking-rack 0, with which the pawl or dog o' engages, as shown in Fig. 1. When the lever K is drawn downward by the operation of the treadle, it and the leverJ will be locked in that position by the pawl or dog 0 until the foot is removed from the treadle. The point o2 of the pawl or dog o' reaches over the top of the connecting-rod G', so that when the treadle is released the spring g' willforce said treadle and rod G' 4upward the extent of slot 7c3, thus tripping the pawl o', whereupon the spring 7c' will replace the levers J K, ready for another operation, the pawl N locking the lever J, as before. Thus the mechanism for operating the air-compressor must return to a position in which the lockingpawl can engage with it before it can be operated again to produce a second discharge. From the plate m2 the coin dropped into the apparatus falls into the box P, and when two or more receptacles C are used I provide the knob b with a disk b3, on which the names or numbers of the different perfumeries may be stamped in line with the apertures c, and I use a stationary pointer b4 to indicate the position to which the'disk should be turned to get the perfumery selected.

One advantage of my improved apparatus is that the discharge is steady and uniform, j

and is not affected by the varying force which is applied by dierent persons to the treadle or by the rate ofspeed with which the treadle is depressed. The discharge of air coming fromv the expanded reservoir, and being produced by the contraction of that reservoir, is always regular and uniform. It is obvious, however, that the discharge may take place in either of two ways. Before depressing the treadle the disk b3 should preferably be turned to suchra position that no one of the apertures e will be in line with any of the tubes d. After depressing the treadle let the disk b3 be again turned so as so bring one of the apertures e in line with one of the tubes d. The discharge will then take place, and be produced and controlled entirely by the contraction of the reservoir E', and will thus be perfectly regular. On the other hand, if the opening e and tube CZ be brought in line b evfore the treadle is depressed, then the.1d1s. charge will be, to a slight degree, directly influenced by the pressure of the plate H; but even then the discharge will be substantially regular.

While I prefer to use the rubber reservoir E', I may dispense with it and take the current of air directly from the bulb E.

Various parts of my invention maybe employed independently of one another or 1n other combinations, so that I do not limit my claims to the combination of all the parts shown and described.

Having thus described my invention, what I claimas new, andV desire to secure by Letters Patent, is-.
